A probe for surface-resistivity measurement is provided in a surface-resistivity measuring apparatus for measuring a surface resistivity of a target. The probe includes an electrode and a contact portion. The contact portion has a specific resistance larger than the electrode. The contact portion is disposed on the electrode. The contact portion is capable of surface-contact with the target.

In an electronic component placing apparatus, four magazines are mounted on a head, and yet electronic components are housed in each magazine. In this apparatus, by an operation of selectively inserting a suction nozzle into four insertion openings in the magazines, it is possible to load a desired electronic component on a substrate, and this component loading can be repeatedly performed until the housed components are exhausted.

Electronic component placing apparatus

Novel heterocyclic compounds shown by the general formula ##STR1## or the pharmaceutically acceptable salts thereof useful as medicament in particular as antagonist of slow reacting substance of anaphylaxis (SRS-A).

Thiazole compounds as inhibitors of SRS-A

This invention relates to novel heterocyclic compounds structurally characterized by containing a specific heterocyclic group and by the presence of --CH.sub.2 --S--directly bound to the specific heterocyclic group. These heterocyclic compounds are useful as medicines, particularly as antagonists of SRS-A (slow reacting substance of anaphylaxis).

Heterocyclic compounds

Heterocyclic compounds and pharmaceutical use thereof

Novel phenylene derivatives shown by the general formula ##STR1## where A represents a hydrogen atom, a phenyl group or a phenoxy group, n represents an integer of 3 to 10, R.sub.1 represents a hydrogen atom or a lower alkoxy group, X.sub.1 represents --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --CONH--, B represents ##STR2## wherein R.sub.2 represents a hydrogen atom, a halogen atom, a nitro group, etc.), ##STR3## (wherein R.sub.3 represents a hydrogen atom, a hydroxyl group or a lower alkoxy group), X.sub.2 represents --CH.dbd.CH--, --CH.sub.2 CH.sub.2 --, etc. and D represents a carboxy group, a lower alkoxycarbonyl group or ##STR4## which are useful as drugs, particularly SRS-A(slow reacting substance of anaphylaxis) antagonist, i.e. they are useful as prophylaxis and treatment for various allergic diseases (e.g. bronchial asthma, allergic rhinitis, urticaria) or, ischemic heart diseases, inflammation, etc. induced by SRS-A.

Phenylene derivatives, compositions and use

A memory access control apparatus according to the present invention which controls an IC memory of which is under the control of a BIOS in the same manner as in a normal disk unit. External file units including the IC memory, a floppy disk unit, a hard disk unit, and the like are assigned a series of drive numbers. Registers store parameters for using the IC memory as an external file, and an access address and a transfer length of the IC memory are expressed in a sector form. The BIOS receives the access address and the parameters, translates the address into a byte form address, and transfers data to a corresponding area.

Thiadiazole compounds as antagonists of SRS-A

Thiadizazole compounds as antagonists of SRS-A

A catechol derivative represented by the formula ##STR1## The compounds of this invention are useful for the prophylaxis and treatment for various allergic diseases, ischemic heart diseases and inflammations caused by slow reacting substance of anaphylaxis (SRS-A), since the compounds inhibit very potently the formation and release of SRS-A.

Catechol derivatives and pharmaceutical compositions thereof for

A novel 2-phenylimidazo[2,1-b]benzothiazole derivative shown by the following formula ##STR1## or a salt thereof which possesses an immunoregulatory action and is useful as an antiallergic agent, an antiasthmatic, and a suppressant of rejection at tissue transplantation and skin graft.
